Alexandru Gagniuc	928a8be794	lib: ecdsa: Implement UCLASS_ECDSA verification on target ... Implement the crypto_algo .verify() function for ecdsa256. Because it backends on UCLASS_ECDSA, this change is focused on parsing the keys from devicetree and passing this information to the specific UCLASS driver.

Alexandru Gagniuc	eb22759e2b	lib/ecdsa: Use the 'keydir' argument from mkimage if appropriate ... Keys can be derived from keydir, and the "key-name-hint" property of the FIT. They can also be specified ad-literam via 'keyfile'. Update the ECDSA signing path to use the appropriate one.

Alexandru Gagniuc	ed6c9e0b66	lib: Add support for ECDSA image signing ... mkimage supports rsa2048, and rsa4096 signatures. With newer silicon now supporting hardware-accelerated ECDSA, it makes sense to expand signing support to elliptic curves. Implement host-side ECDSA signing and verification with libcrypto. Device-side implementation of signature verification is beyond the scope of this patch.
